IMPROVEMENTIN COMBINED CISTERN TOPS AND FILTERS.

Specitication forming part of Letters Patent No. 158,605, dated January12, 1875,' application led To all whom it may concern! Be it known thatI, EPHEAIM D. STACEY, of Corsicana, in the county of Navarro and Stateof Texas, have invented certain new and useful Improvements in CombinedGistern Top and Filter; andI do hereby declare the following to be afull, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

Thenature of my invention consists in the construction of a covering forcisterns, which has combined therewith a ilter and all the necessaryappliances for convenience, as will be hereinafter more fully set forth.

In the accompanying drawing, Figure l is a plan view of my invention.Fig. 2 is a similar View with the cover removed. side view, and Fig. 4 avertical section of the same.

A represents a disk of cast-iron of other suitable material, and of anydesired size, to rest upon the top of the arch or mouth ofthe cistern.Out of the center ot' this disk is cut an opening in circular form, lessa segment ot one'i'ourth the circle, which opening` is for the purposeof receiving the conical-shaped filter B. In that part of the disk whichforms the segment mentioned is a small aperture, a, for the insertionvof the pi'pe or stock of a pump. Z) b are staples, inserted in the diskA opposite each other, as shown. The h'lter B is made of cast-iron orother suitable material, in the shape of an inverted cone or funnel,with one side at, so that it may iit the opening in the disk A. The edgeof thelter is flared for the purpose of resting on and being supportedby the disk. The bottom of the iilter is perforated, as shown, alongabout two-thirds of Fig. 3 is a July 9, 1874.

the sides toward the top, for the purpose of allowing the water toescape from the pipe conveying the Water into the cistern'. The cavityof the cone or filter is to be lled with charcoal or other suitablefiltering substance, through which the water running from the roofthrough the pipe may be filtered for purifying the water. On the insideof the filter and opposite each other are handles d d, for lifting thelter from its place when necessary to clean it or replace new charcoal.The cover is made in two parts, C and D, hinged together on a rod, 7L,the ends of which pass under the staples b b. The part C of the coverhas an opening, t', of suitable size to receive the water-pipe from theroof.

The part D may be turned back for the purpose of receiving waste waterfrom the pump, the spout of which should be placed directly over thispart of the cover.

This cistern cover and filter is cheap, easily manufactured, anddurable, and it may be applied to any cistern without much expense.

Having thus fully described my invention,

what I claim as new, and desire to. secure by Letters Patent, is

The combination of the disk A, provided with opening a and staples b b,the conical perforated filter B, and the cover C D, having' opening i,all constructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 26th day of May, 1874.
